LOCOMOTIVE.

FJPECIFICATION forming part of Letters Patent No. 352,60] dated November 16, 1886.

Application filed May 20,1886. Serial No. 202,805. (No model.) I

To aZZ whom it may concern:

Be it known that I, WILLIAM ANDERSON, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of 0010- rado, have invented certain new and useful Improvements in Locomotive-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in locomotive-engines, in which the weight of the boiler is supported upon springs and held in such a position that the expansion and con traction of the boiler acts independently of the other mechanism, in conjunction with double engines on each side of the boiler, together with four rails to travel upon.

The objects of my improvements are, first, in virtue of the great power obtained from the peculiar construction of my engine and the necessary weight thereof, I support the heaviest part on springs placed at suitable intervals under the boiler; second, to afford facilities for the expansion and contraction at the points of support, which are so constructed that they can be readily removed independently of the other mechanism; third, to afford facilities for the support of the boiler and secure it independently to the main engineframes. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical side view of the locomotive-engine, showing the supports under the fire-box, with a portion of the couplingrod broken. Fig. 2 is a top View of the engine, showing the plan of support and crossbars connecting the side frames of the double engine. Fig. 3 is an end view of the crossbar at the fire-box door, showing the springs. Fig. 4. is a crosssection through A B. Fig. 5 is a side elevation of boiler at AB, with crosssection of springsupport. Fig. 6 is a crosssection through 0 D. Fig. 7 is an end view of the cylinder or front end of engine, showing the dovetail arrangement for expansion and contraction. Figs. 8, 9, 10, and 11 are enlarged views of the front end or smoke-box support of the boiler.

Similar letters refer to similar parts through the several views.

The plates E E and the end distant piecesF F constitute the frame to which the supports or cross-pieces A, A and A are secured by means of the bolts a a a. The cross-bars A and A have pins D,that carry the coil-springs d and retain them in proper position longitudinally and in the direction of the boiler. Pins R pass through the cross-bars A and A and loosely into the angle-plate P. The an-' gle-plate P forms part of the boiler and moves i nthe direction of expansion with the boiler, and is placed in proper position so that when removing the boiler from its frame the pins will allow plate P to pass. The holes for pins R in the plate P are oblong in the vertical direction,to allow the spring to move freely, as shown in Fig. 11.

The fire-box cross-bar A is provided with springs evenly distributed. plate P are made to fit the pins sufficiently loose to allow the vertical motion due to the spring only and hold the boiler rigidly.

The front or smoke-box end of the boiler T is supported in a saddle-frame, H, which is secured to the cross-beam M by bolts f. To the boiler a corresponding sliding frame, O,is riveted by the rivets O, which move at pleasure in the dovetail groove G.

On each side of the two frames E are placed two cylinder-engines, B 13*, shown in Fig. 1, and end view of Fig. 7. Only one cylinder is shown in Fig. 2, with its connecting-rod a a broken.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is

1. In a locomotive engine and boiler, the combination of the cross-bar A, secured to the side frames, E E, together with the plates P, which have recesses or oblong holes 1 to allow the action of the spring, and the pin R, secured to the cross-bar A, substantially as described.

2. In a locomotive engine and boiler, the combination of the cross-bar A with frames E E and pin D, with the springs d, together with the pins R, substantially as described and set forth.

3. In a locomotive engine and boiler, the combination of the frames E E and distant The holes in pieces F F with crossbar Af, with its'pins D In testimony whereof Iaflix my. signature in 10 and springs d, and plate P, substantially as the presence of two Witnesses. described and set forth.

4. In a locomotive engine and boiler, the W'ILLIAM ANDERSON. 5 combination of the saddle H With the dovetail groove G and sliding piece 0, secured to Witnesses: boiler T by the rivets O, and the saddle-bolts Y WARD H. LAMON, f f, fastened to the beam M, substantially as B. F. RICE. described and set forth.
